Specifications

Installation (Setup)

IMPORTANT: Installation should only be performed by a certified HVAC professional.

1. Power Disconnection: Turn off all electrical power to the furnace at the main breaker or fuse box. Verify power is off using a voltage tester.
2. Access: Locate and access the existing draft inducer motor within the furnace unit.
3. Disconnection: Disconnect all electrical wiring from the old motor. Carefully note or photograph the wiring configuration for correct re-connection.
4. Removal: Unbolt or unmount the old draft inducer motor from its housing or mounting bracket.
5. Inspection: Inspect the mounting area and surrounding components for any damage or debris. Clean as necessary.
6. New Motor Installation: Mount the new Fasco D9868614 motor securely in place, ensuring all mounting points align.
7. Wiring: Reconnect the electrical wiring to the new motor, ensuring connections are tight and correct according to the furnace's wiring diagram and your previous notes.
8. Testing: Restore power to the furnace. Initiate a call for heat to test the operation of the new draft inducer motor. Verify proper exhaust ventilation and listen for unusual noises.
9. Final Checks: Ensure all panels are securely re-installed and no tools or debris are left inside the furnace.

Operation

The draft inducer motor operates automatically as part of the furnace's combustion cycle. When the thermostat calls for heat, the furnace control board activates the draft inducer motor first. This motor creates a negative pressure (draft) in the combustion chamber, pulling in fresh air for combustion and expelling exhaust gases. Once sufficient draft is established, a pressure switch signals the control board to allow the igniter and gas valve to activate, initiating the heating process. The motor continues to run throughout the heating cycle and for a short period after the gas valve closes to purge remaining combustion gases.

Maintenance

Regular maintenance of your furnace, including the draft inducer motor, is crucial for longevity and efficiency. It is recommended that a qualified HVAC technician perform annual furnace inspections and maintenance.

• Annual Inspection: Have a professional inspect the draft inducer motor for signs of wear, corrosion, or unusual noise during your annual furnace tune-up.
• Cleaning: The inducer motor housing and impeller can accumulate dust and debris over time. A technician can safely clean these components to ensure unrestricted airflow.
• Vibration Check: Ensure the motor is securely mounted and not vibrating excessively, which could indicate worn bearings or imbalance.
• Electrical Connections: Verify that all electrical connections to the motor are clean and secure.

Troubleshooting

If your furnace is not operating correctly, the draft inducer motor may be a contributing factor. Always consult a qualified HVAC technician for diagnosis and repair.

Note: Always disconnect power before attempting any inspection or repair. If you are not a qualified technician, do not attempt repairs yourself. Contact a professional.
